Science & Technology – Space Technology

Why in News?

NASA engineers have implemented a major “Big Bang” power-saving upgrade on Voyager 2, extending the operation of its remaining scientific instruments by at least one additional year. 

Key Facts

• Launched: 20 August 1977 by NASA. 
• Primary mission: Exploration of Jupiter, Saturn, Uranus and Neptune. 
• It is the only spacecraft to have visited Uranus and Neptune. 
• 2018: Voyager 2 crossed the heliopause and entered interstellar space. 
• It studies the interstellar medium, including plasma, magnetic fields and energetic particles. 
• Powered by Radioisotope Thermoelectric Generators (RTGs); their electrical output gradually declines with time. 
• The latest upgrade redistributed power from less-essential/heating systems while keeping three science instruments operational. 

Important Concept: Heliosphere

The heliosphere is the vast bubble formed by the solar wind around the Solar System. The heliopause is its outer boundary where solar-wind influence gives way to the interstellar medium.

UPSC Angle

Solar wind → heliosphere → heliopause → interstellar medium → deep-space exploration.

Prelims Trap: Voyager 2 has entered interstellar space, but this does not mean it has left the Solar System in the broad gravitational sense.

Environment & Ecology + Tribal Affairs

Why in News?

The Tribal Council of Great and Little Nicobar has raised concerns over alleged remarks that the Shompen should adopt a “modern lifestyle” in the context of the Great Nicobar Island (GNI) Project. The issue highlights tensions between infrastructure development, tribal rights and conservation. 

Key Facts

• Shompen: An indigenous Particularly Vulnerable Tribal Group (PVTG) inhabiting Great Nicobar Island. 
• Traditionally follow a largely hunter-gatherer and forest-dependent lifestyle. 
• They have relatively limited interaction with the outside world, making disease exposure and cultural disruption important concerns. 
• Great Nicobar: Part of the Nicobar Islands, located close to major Indian Ocean–Malacca Strait sea routes. 
• The GNI Project envisages major infrastructure including an International Container Transshipment Terminal at Galathea Bay, airport, power facilities and township. 
• The project has generated debate over forest diversion, biodiversity, tribal reserves and indigenous rights. 

Legal/Constitutional Link

The Andaman and Nicobar Protection of Aboriginal Tribes Regulation, 1956 provides a framework for protecting indigenous communities and regulating access to tribal areas.

UPSC Angle

PVTG protection → tribal autonomy → development-induced ecological/social impacts → sustainable development.

Prelims Trap: Shompen are associated with Great Nicobar, not the Andaman Islands.

Why in News?

A recent CAG Performance Audit has flagged major shortcomings in the implementation of the Green India Mission (GIM) during 2015–16 to 2024–25, including inadequate funding, weak convergence and poor monitoring. The audit covered interventions in 16 States/UTs. 

Green India Mission – Key Facts

• Launched: 2014 as a Centrally Sponsored Scheme. 
• One of the eight missions under the National Action Plan on Climate Change (NAPCC). 
• Nodal Ministry: Ministry of Environment, Forest and Climate Change (MoEFCC). 
• Objectives: 
  • Increase and improve forest & tree cover 
  • Enhance biodiversity and ecosystem services 
  • Improve carbon sequestration 
  • Strengthen forest-based livelihoods 
• Original targets: 
  • Increase forest/tree cover over 5 million hectares 
  • Improve quality of cover over another 5 million hectares 
  • Enhance annual CO₂ sequestration by 50–60 million tonnes. 

CAG Findings

The audit reported a 97.57% shortfall in the targeted increase in forest cover and a 91.87% shortfall in improving forest-cover quality. Major concerns included poor financial planning, weak inter-scheme convergence and inadequate monitoring. 

UPSC Angle

NAPCC → Green India Mission → forest restoration → carbon sequestration → India’s climate commitments.

Prelims Trap: GIM is one of the eight NAPCC missions, not a standalone climate programme.

Economy – Taxation & Financial System

Why in News?

The government has introduced the Foreign Assets of Small Taxpayers–Disclosure Scheme (FAST-DS), providing a limited window for eligible taxpayers to disclose certain previously undisclosed foreign assets/income. The scheme opened on 16 August 2026 and remains available until 31 December 2026. 

Key Features

• Target: Small taxpayers with certain undisclosed foreign assets/income. 
• Eligibility ceiling: Foreign assets covered up to ₹5 crore. 
• Provides a simplified mechanism to regularise eligible past non-disclosures. 
• Taxpayers can disclose assets such as foreign bank accounts, financial investments and other specified overseas assets. 
• Designed to improve voluntary compliance and financial transparency while reducing the compliance burden on small taxpayers. 
• Important distinction: this is a limited disclosure window, not a general amnesty for serious tax evasion or undisclosed black money. 

Black Money Act

The scheme must be understood alongside the Black Money (Undisclosed Foreign Income and Assets) and Imposition of Tax Act, 2015, which provides the statutory framework for taxation and penalties relating to undisclosed foreign income/assets.

UPSC Angle

Undisclosed foreign assets → tax evasion → Black Money Act → voluntary disclosure → improved tax compliance.

Prelims Concept: FCNR(B) deposits are foreign-currency denominated deposits maintained by NRIs with Indian banks; the special RBI swap facility was intended to encourage foreign-currency inflows and help banks manage exchange-rate exposure.

GS II – Polity and Governance
Federalism, Electoral Reforms, and Parliamentary Democracy

Introduction

One Nation, One Election (ONOE) seeks synchronised Lok Sabha and State elections, but critics argue it may weaken federalism and parliamentary accountability. The debate goes beyond cost and governance efficiency, raising concerns about constitutional balance, State autonomy and democratic choice.

The Constitutional and Federal Concerns

Erosion of State Autonomy

• Federal Structure: India is a Union of States with a quasi-federal structure. Synchronisation would undermine the autonomy of State governments.
• State Elections: Have distinct political rhythms and local issues that are diluted when tied to national polls.
• Constitutional Guarantees: State legislatures have fixed terms (Article 172), and imposing a uniform cycle requires constitutional amendments that erode this guarantee.

Distortion of Electoral Mandates

• National vs. State Issues: Voters often choose differently for national and State governments. Synchronisation would force a binary choice on issues that are not linked.
• Coattails Effect: A wave in favour of a national party could sweep in State governments that do not reflect local preferences, distorting democratic mandates.
• Reducing Accountability: Voters cannot effectively hold State governments accountable if their fate is tied to national political winds.

Weakening Democratic Accountability

• Permanent Campaign Mode: Even with synchronised elections, mid-term vacancies and no-confidence motions would require by-elections, breaking the uniformity.
• Governance Paralysis Narrative: The claim that frequent elections cause governance paralysis is exaggerated. India has managed multiple elections while maintaining governance.
• Financial Argument: The cost of elections, while significant, is not the primary factor in democratic governance. Centralisation of electoral cycles saves money but costs federalism.

The Mechanics of the Parliamentary System

Parliamentary vs. Presidential Logic

• Presidential System: Fixed terms for the executive; synchronisation is mechanically feasible.
• Parliamentary System: The executive is responsible to the legislature. A government can fall mid-term, leading to premature elections.
• Constitutional Friction: ONOE attempts to impose presidential-style fixed terms on a parliamentary system, creating a fundamental mismatch.

The Inevitability of Mid-Term Polls

• No-Confidence Motions: Can bring down a government, necessitating fresh elections.
• Hung Assemblies: May require premature polls.
• Resignations/Deaths: Vacancies create inevitable by-elections, breaking any synchronisation.

Administrative Convenience vs. Democratic Substance

• Primacy of Convenience: The ONOE proposal prioritises the convenience of the administration over the substantive democratic rights of States.
• Diversity of Political Rhythms: India’s political diversity requires that elections reflect local conditions, not a centralised timeline.

Weaknesses and Risks

• Federal Erosion: Undermines the distinct identity of State politics.
• Distorted Mandates: Links local issues to national popularity.
• Logistical Challenges: Synchronising schedules requires constitutional amendments and political consensus.
• Anti-Federal: Goes against the spirit of cooperative federalism.

Comparative Perspective

• Presidential Systems: The U.S. has fixed terms for President and Congress but not for State legislatures.
• Parliamentary Systems: Most parliamentary democracies do not have fully synchronised national and State elections.

Conclusion

One Nation, One Election (ONOE) may improve administrative efficiency, but critics fear it could weaken federalism, State autonomy and parliamentary accountability. India’s diverse political realities require flexibility in electoral cycles. Democratic mandates should take precedence over administrative convenience.

Practice Question

1. The ‘One Nation, One Election’ proposal prioritises administrative convenience over democratic substance, and poses a threat to India’s federal architecture. Critically examine. (250 words, 15 marks)

GS III – Economy
Exchange Rate Management, External Sector Vulnerabilities, and Banking Risks

Introduction

The RBI’s $52.3 billion FCNR(B) inflow helped stabilise the rupee by boosting foreign-currency liquidity. However, this is a temporary solution, not a structural cure. Hedging costs borne by the RBI and future deposit maturities shift risks to the public balance sheet and banking system, creating potential repayment and asset-liability pressures.

The FCNR(B) Window: How It Works and What It Achieved

Mechanism

• FCNR(B) Deposits: Non-resident Indians hold foreign currency with Indian banks, free of rupee risk, with tax-free interest and full repatriation.
• Swap Facility: Banks raise 3-5 year deposits, swap dollars with RBI, which absorbs hedging costs.
• High Yields: Once hedging cost is lifted, banks offer dollar rates near 6-7.5%, some adding leverage of 9-19 times.
• Carry Trade: Wealthy depositors borrow abroad and place funds in India at protected high yields, with currency risk removed.

Scale and Speed

• Mobilisation: $52.3 billion between June 8 and August 13, 2026.
• Window Closure: RBI closed FCNR(B) swap window a month early—seen as a vote of confidence.

Why It Was Needed

• Rupee Pressure: Asia’s worst-performing currency in 2025-26; FPI outflows.
• Expectations Loop: Once investors believe depreciation is one-way, good data stops persuading them. Breaking the loop requires making bets against the rupee expensive.

The Risks: Relocated, Not Eliminated

Public Balance Sheet Exposure

• Hedging Cost Absorption: When RBI absorbs hedging costs, the exposure moves onto the public balance sheet.
• Implicit Liability: The state bears the cost of protecting depositors from currency risk.

Banking Sector Asset-Liability Mismatch

• Maturity Mismatch: Banks raise 3-5 year deposits and lend against them, creating an asset-liability mismatch.
• Risk Resurgence: A visible currency problem today can become a less visible banking problem tomorrow.

Future Repayment Obligations

• Maturing Deposits: Every dollar arriving now must be repaid in 3-5 years.
• Rollover Risk: If deposits are not rolled over, capital outflow could pressure the rupee.

Current Account Deficit Context

• CAD: India slipped into a current-account deficit in May 2026.
• Not a Durable Source: FCNR(B) deposits are a balance-of-payments stabiliser, not a durable source of dollars.

Borrowed Time vs. Earned Dollars

Strengths of the RBI’s Move

• Decisive Action: Stabilised the rupee in the short term.
• Diaspora Leverage: Proved India can summon diaspora dollars quickly when needed.
• Cushion: Large reserves, services exports, and remittances provide a buffer.

Weaknesses and Risks

• Confidence is Purchased: Flows surged only after the subsidy appeared—confidence that materialises only after the price is raised is not confidence, it is a purchase.
• Risk Transfer: The scheme does not make rupee risk disappear; it relocates it to the public balance sheet and banking system.
• Maturity Wall: Repayment obligations will strain external finances.

The Real Solution

• Earn Dollars: Build export-surplus sectors, attract FDI, cut energy import dependence, and treat tourism as a foreign-exchange industry.
• No Substitute: If India earns too few dollars, no better way of borrowing will solve it.

Way Forward

• Use the Window: Leverage FCNR(B) inflows for export and FDI reforms. 
• Cut Import Dependence: Boost renewables and domestic manufacturing. 
• Expand Exports: Promote high-value services, electronics, pharma and tourism. 
• Manage Risks: Monitor bank leverage and prepare for FCNR(B) maturities through prudent rollover strategies.

Conclusion

The RBI’s $52.3 billion FCNR(B) swap facility stabilised the rupee and curbed speculative pressure, but the stability is temporary. With deposits maturing in 3–5 years, risks have shifted to the public balance sheet and banking system. India must use this window to boost exports, attract FDI and reduce energy-import dependence. Earning more dollars is the durable defence of the rupee.

Practice Question

1. The FCNR(B) surge has given the rupee breathing space, but it has merely relocated risk rather than eliminated it. Critically examine the implications of the RBI’s swap facility for India’s external sector and banking stability, and suggest sustainable solutions for rupee defence.
